crypto: essiv - use crypto_shash_tfm_digest()
Instead of manually allocating a 'struct shash_desc' on the stack and calling crypto_shash_digest(), switch to using the new helper function crypto_shash_tfm_digest() which does this for us. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
